In digital input mode, the user has to select the lines/port through DAQmx Global Channel to get digital output. The input of 3.3 V is given by analog output port to digital input port, so that lines/port indicator goes high.
There are 13 lines of digital I/O and can be operated as all simultaneously. These lines are divided into 3 ports, port 0 with 8 lines, port 1 with 4 line, and port 2 with 1 line.
Hardware and Software Requirements
NI USB-6002, LabVIEW
Steps to Implement or Execute Code
1. Connect USB-6002 through USB port.
2. Connect external DC of 3.3 V with respect to Digital Input Ground (DI GND).
3. Download NI-DAQmx 18.0.0, Execute sample code "USB6002-DI-port" and run it.
4. Monitor the subsequent DI line status, High / Low.
